Data mining in public code platforms such as GitHub, has been widely used to compromise developer’s privacy. Due to inexperience or laziness, a lot of personal secret are left hardcoded in their source code which is then made public. There is no need for hacking skills to exploit this kind of vulnerability, sometimes is easy to find some credentials just using the GitHub search bar. In 2016 Uber had to sustain a massive data leak affecting 57 million customers that revealed sensitive information such as names, email address and phone numbers. The source of the attack was leaked credentials found in a private GitHub repository.
